I prefer the paper dictionary. You may say electronic dictionary is much more convenient, easy to use and light-weight. But I find that when I look up the new words in the paper dictionary and write them down on my notebook, I can remember better.
For the paper dictionary, probably much lighter and easy to carry around. While for the electronic dictionary, maybe much more detailed and accurate.
I mainly used the bilingual dictionaries, like Advanced Oxford English-Persian and Persian-English Dictionary or the Longman Dictionary and some electronic dictionaries my teachers recommended. Each has its advantages.
I use my dictionary nearly every day. My major is English, so whenever I encounter some words I don' t know, I will look them up either in the paper dictionary or the electronic dictionary.
